Here is the latest one to get a good make over..the Y idler for the Open Y carriage assembly. The old one was a bit confusing and flimsy compared to this new one. Granted we are still using 2 bolts to tighten the belt for the Y axis, it’s efficient and gets the job done quite well..

P.S. – If you have the older version and you have it working for you then you don’t NEED to do this change(unless you feel like doing it).

A few other parts that have been modified/improved that will soon be added here and to the official BoM(along with vitamin counts):

I have recently been working on designing the parts needed to build a Linear Actuator out of just the PBC GST rail and slide.

Here you see the original idea I had came up with. I ended up tossing this design but you get the idea. The drive screw is a 5/16th threaded rod from Lowes, for like 10$ if I recall. This helps keep the overall price down, which is the goal here..that and AMAZINGLY PRECISE PRINTS.

Moving on, I eventually got a rough design done that worked well during prototyping. I’m really excited about this design because I think it might work better then even my Open X/Y designs.

(6 parts actually)

So here is the design I have been testing and getting great results. Couple more tweaks here n there and I think it will be ready to move to the next phase..PRINTING.

Thanks for checking this out and stay tuned for more, this month is going to be a fun one. 🙂 -papabur

Jan. News:

So, needless to say, January was a crazy month for me and it has taken quite a bit of work to keep the store going and my motivation up after everything thats happened in the last 6-8 weeks. Between hospital visits to the V.A., friends loosing their houses, packages of Mobious stock stolen off porches after being sent to wrong(old) address, and plenty of other things i was not counting on happening or expecting of/prepared for...

I'm still here though and orders are still going out, in fact we sold 3 sE1X kits for the month of January which isnt bad at all!! I suppose it always rains before a rainbow right? :D

..I have not had much time to work on Solidworks but I do have a new project underway that I would like to share with everyone. In the last week or so I have been working on a design for a mechanical linear rail system using PBC Linear's GST( Glide Surface Technology). The following link is to PBC Linears website where it explains, in more detail, the advantages to this style of linear rail

. :: UGA Low Profile Uni-Guide Linear Slide ::
I have decided to try and create a mechanical linear rail operation out of the PBC rail/slide, heres a assembly picture of what I've managed to get done so far. The idea is to run lead screws along the bottom side of the rail where the car(slide) will have a bracket on the bottom, the threaded rod will run through said bracket, moving the car/slide back and forth with the hope for very high precision.

I will post more pictures once I have it finished and ready for prototyping.

So I have had a few customers mention rust on their smooth rods, and this is common when dealing with Drill Rod. Drill Rod is hardened and is also drawn to a precision tolerance. The composition of the alloy is a more important factor than any sort of plating. Typically hardened tool steel is a high carbon alloy with chromium and molybdenum as well as manganese and other elements.

Here is a solution I have found to work for me, below I will have a short pictured tutorial showing what type of sand paper to use and how it should look once your finished.

Sand Paper I used( as shown to the left) was P150. I’m not real familiar with automotive sand paper and their gauging system but I’m sure if you can find something even finer, you would get great results..

I recommend dry sanding with something AT LEAST this grade. I simply sat on the floor(Indian style) and slowly rotated the rod with one arm while the other was sanding.

After you have them sanded down, I recommend coating them in some lubricant and wiping any left over sanding debree ([PROTIP]A sugar free Rockstar may also help this procedure.)

“unlike the typical encased 3d printer, the team’s phone-based device prints objects in the open, as long as it’s placed in a dark corner.”

“This isn’t the first mention of a smartphone in the context of 3D printing.Solido3D, an Italian rapid prototyping company, announced a phone-based 3D printer called OLO in October. While the company is yet to reveal how OLO works, Taiwan Tech’s 3D printer, which currently lives in the lab, has been able to create a hollow ball that’s about 100 microns thick.”

This is a 3D printed EZ Spin Motor. It turned out being a very clean and nice running build. I also explain how to properly wire up an EZ Spin Motor. This thing would run for a very long time on a 5v super capacitor.\

Hey guys, just wanted to share this with everyone, its called Makerbox!

from Makerbox site:

“A Maker Box is a monthly subscription box filled with all kinds of awesomeness for makers and tinkerers. For $30 bucks you get about $50 worth of components, modules, development boards, and all kinds of amazing. Many of the modules are designed for Arduino and each month we release a blog explaining how to use the components with an Arduino while also providing sample code and libraries. ”

I have been working myself to death trying to get this design done, and done right. The plan is to eventually offer a dual extruder se1x complete kit variation as well as a upgrade possible for previous customers. I even started a new carriage from scratch for this project. I’m considering making quick release for tool head changes(such as changing out a dual extruder mount for a single and more) but for now I’m just focused on getting the dual extruder mount made. 🙂 heres what I got so far.

new X carriage, dubbed the grasshopper or mantis..haven’t decided yet..what do you think?
